Simulating Exceptional Non-Hermitian Metals with Single-Photon Interferometry
Kunkun Wang, Lei Xiao, Jan Carl Budich +2
We experimentally simulate in a photonic setting non-Hermitian (NH) metals characterized by the topological properties of their nodal band structures. Implementing nonunitary time…
Observation of non-Bloch parity-time symmetry and exceptional points
Lei Xiao, Tianshu Deng, Kunkun Wang +3
Parity-time (PT)-symmetric Hamiltonians have widespread significance in non-Hermitian physics. A PT-symmetric Hamiltonian can exhibit distinct phases with either real or complex ei…
Non-Hermitian Kibble-Zurek mechanism with tunable complexity in single-photon interferometry
Peng Xue, Lei Xiao, Dengke Qu +7
Non-Hermitian descriptions of quantum matter have seen impressive progress recently, with major advances in understanding central aspects such as their topological properties or th…
Experimental realization of a quantum image classifier via tensor-network-based machine learning
Kunkun Wang, Lei Xiao, Wei Yi +2
Quantum machine learning aspires to overcome intractability that currently limits its applicability to practical problems. However, quantum machine learning itself is limited by lo…
Experimental entropic test of state-independent contextuality via single photons
Dengke Qu, Pawel Kurzynski, Dagomir Kaszlikowski +5
Recently, an inequality satisfied by non-contextual hidden-variable models and violated by quantum mechanics for all states of a four-level system has been derived based on informa…
